Specification of Letters Patent.

Patented July 3, 1906.

Application filed January 19,1906. Serial No. 296,851.

To all 7071,0712, it WWI/:1] concern:

Be it known that I, GEORGE E. HASSMANN, a citizen of the United States,residing at Springfield, in the county of Sangamon, State of Illinois,have invented certain new and useful Improvements in Door-Checks; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to builders hardware, and more particularly todoor-checks, and has for its object to provide a device of this kindwhich will be extremely simple and cheap and which will be arranged tohold a door at any desired point of its movement.

Other objects and advantages will be apparent from the followingdescription.

In the drawings forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views,Figure l is a vertical section of a door, showing the present inventionapplied thereto and in operative position. Fig. 2 is a view of the doorin elevation, the check being in operative position. Fig. 3 is atransverse section taken through the door, the plate, and the rodhorizontally. Fig. 4 is a detail view of a lower end of the rod and thefloorengaging member, showing the connection therebetween. Fig. 5 is adetail view show ing the rod connected with the door-knob for movementwhen the latter is revolved.

Referring now to the drawings, there is shown a door 5, having avertical passage 6 formed therein adjacent to its free edge and openingthrough its lower edge, the door having a vertical slot 7 thereincommunicating with the passage 6 at the upper end thereof, and the slothas at its upper end a lateral extension 8.

Secured vertically within the passage 6, at.

the lower end thereof and at the side of this passage which lies awayfrom the direction of movement of the door into closed position, thereis a plate 9, having transverse serrations 10, and disposed looselywithin the passage there is a vertical rod 11, having a floorengagingblock 12 at its lower end of rubber or similar material. This block isdetachably connected with the rod, so that it may be removed whenreplacement is necessary.

The rod 11 has transverse serrations 13 thereon, arranged for engagementof the sermovement, and at its upper end the rod 11 is turned laterallyto extend outwardly through the slot 7, the outer end of thelaterallyturned portions having a head 14 thereon. The laterally-turnedportion may be moved into the lateral extension 8 of the slot 7 and whenthus engaged holds the rod at the upward limit of its movement and withthe member 12 out of engagement with the floor.

WVhen the check is to be moved into operative position, the rod 11 ismoved downwardly to engage the member 12 with the floor, when thetendency of the door to close itself will bring the plate 9 against therod 11, intermeshing the serrations 10 with the serrations 13, and thusholding the rod with the member in operative position. It will be seenthat as the floor-engaging member is worn away the rod may be movedfarther downwardly to compensate for such wear.

It will be understood that the head 14 lies in spaced relation to theouter surface of the door to permit of lateral movement of the rod 11within the passage.

In Fig. 5 there is shown a form of the invention in which the rod 11 isconnected with the sleeve a of a door-knob A by means of a flexibleconnection B for vertical movement of the rod to bring the block 12 outof engagement with the floor when the knob is revolved. It will bereadily understood that the door is first moved to bring the serrations10 and 13 out of intermeshing engagement, and the knob is then revolvedto raise the rod 1 1.

What is claimed is 1. The combination with a door having a verticalpassage therein openin through its lower edge, of a plate disposedwithin the passage at one side thereof and having transverse serrations,a rod disposed within the passage for vertical movement, afloor-engaging member carried by the rod, means for holding the rod withthe floor-engaging member in inoperative position, said rod havingserrations for engagement with those of the plate and being movable atits lower end with respect to the'door to engage its serrations withthose of the plate to hold the rod against upward movement.

2. The combination with a door, of a rod connected therewith, afloor-engaging member carried by the rod, said rod being arranged formovement to bring the floor-engaging member into and out of operativeporations 10 to hold the rod against vertical 1 sition, means forholding the rod against IIO vertical movement, said rod being movable Intestimony whereof I afi iX my signature litterally at its lower end withrespect to tllie in presence of two witnesses.
